NAME top

       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS top


       #include <pcre2.h>

       int pcre2_jit_match(const pcre2_code *code, PCRE2_SPTR subject,
         PCRE2_SIZE length, PCRE2_SIZE startoffset,
         uint32_t options, pcre2_match_data *match_data,
         pcre2_match_context *mcontext);

DESCRIPTION top


       This function matches a compiled regular expression that has been
       successfully processed by the JIT compiler against a given
       subject string, using a matching algorithm that is similar to
       Perl's. It is a "fast path" interface to JIT, and it bypasses
       some of the sanity checks that pcre2_match() applies.  Its
       arguments are exactly the same as for pcre2_match(), except that
       the subject string must be specified with a length;
       PCRE2_ZERO_TERMINATED is not supported.

       The supported options are PCRE2_NOTBOL, PCRE2_NOTEOL,
       PCRE2_NOTEMPTY, PCRE2_NOTEMPTY_ATSTART, PCRE2_PARTIAL_HARD, and
       PCRE2_PARTIAL_SOFT. Unsupported options are ignored. The subject
       string is not checked for UTF validity.

       The return values are the same as for pcre2_match() plus
       PCRE2_ERROR_JIT_BADOPTION if a matching mode (partial or
       complete) is requested that was not compiled. For details of
       partial matching, see the pcre2partial page.

       There is a complete description of the PCRE2 native API in the
       pcre2api page and a description of the JIT API in the pcre2jit
       page.
